UB-Lab product family - Versatile ultrasonic profilers

UB-Lab profilers allow accurate velocity profiles measurements from the laboratory flume to the industrial process.

Advantages

  • High spatial and temporal resolution
  • Large transducer choice
  • Fine frequency tuning
  • Web interface

The compact and splash-proof (IP65) enclosure of the UB-Labs is adapted to harsh environments. These scientific instruments can be used within a laboratory as well as in an industrial context (see application for in-line rheometry). They break new ground by offering the user new capabilities in the fields of fluid study and control.

The devices are configured through a dynamic web interface and integrate an internal logger (3Go) which allows the storage of a large amount of data, enabling days or months of monitoring (depending on configuration).

Ethernet communication goes through RJ45 cable. The devices can behave like a DHCP server when connected directly to the computer, or they can be connected to the network and behave like a DHCP client. Depending on the network configuration, connection to the device through WiFi is possible.

The UB-Labs are declines in 4 versions:

The first three versions work in monostatic modus, meaning the same transducer emits bursts and receives the corresponding echoes. This technology is also known as UVP (Ultrasonic Velocity Profiling) or UDV (Ultrasonic Doppler Velocimetry) and provides 1-component velocity profiles (projection on the transducer axis):

  • the UB-Lab S2 offers basic functionalities of the UVP technology. To cover more applications, the expert (X) devices is recommended.
  • the UB-Lab X2 and the UB-Lab X8 allow to measure with respectively up to 2 and up to 8 transducers in monostatic modus. They are able to drive several transducers in a large frequency range (from 800 kHz to 9.4 MHz) and it can therefore be adapted to many kinds of liquids and particles. Like the UB-Flow profilers, they give access to the acoustic turbidity which allows the evaluation of Suspended Sediment Concentration (SSC). It can measure simultaneously velocity and acoustic turbidity profiles.

When equipped with two transducers, they can be used as a high resolution 2C ADCP.

High resolution velocity profile in a pipe filled with sunflower oil

The UB-Lab profiler (UVP) allows accurate velocity profiles measurements on laboratory setups and physical scale models, such as high resolution velocity profiling in oil, in a food processing pipe.


In-line rheometry

In-line rheometry in food processes

In-line rheometry with UB-Lab profiler allows an advanced knowledge of the product quality, which needs to be controlled in many food processes. For example, a real-time, accurate and non-invasive viscosity measurement based on UB-Lab has been developed.
